- You should really leave it to `on` ⚠️
- Turn it to `off` if you have trust issues with the healthcheck. Don't then report issues if the connection is dead though.
- run small check every 60s, from 15s
- small check (icmp/dns) initial timeout from 3s to 10s
- small check (icmp/dns) timeout increase from 1s to 10s
- full check initial timeout increased from 10s to 20s
- full check extra timeout increase from 3s to 10s
- New option: `HEALTH_ICMP_TARGET_IP` defaults to `0.0.0.0` meaning use the VPN server public IP address.
- Options removed: `HEALTH_VPN_INITIAL_DURATION` and `HEALTH_VPN_ADDITIONAL_DURATION` - times and retries are handpicked and hardcoded.
- Less aggressive checks and less false positive detection
